Harvesting tests of high moist wheat grains (30-45%) were made with a head-feeding combine. Time of harvesting, combine settings and drying conditions were evaluated through comparison of operation precision and quality of grains and flour. Experiments demonstrated that 45% of moisture content grains were harvestable with no machine trouble with a chaff rate of the grain outlet less than about 5%, total grain loss of less than about 2%, and damaged grain of less than about 1%. Harvesting of around 40% moisture content grains with rapid drying can provide better quality than harvesting with lower moisture content after rain fall. Harvesting with a low rotation speed of threshing cylinder and normal operational speed improved the flour color. The color differential in comparison to that harvested by binder was less than 0.6.
